The Indian River Mosquito Control District (IRMCD) is an independent taxing district which was created in 1925 by an act of the Florida Legislature. It was the first mosquito control program created in Florida and coincided with the creation of Indian River County. Since that time, the District has worked to provide the best in scientifically valid mosquito control methods with special attention paid to the environmental sensitivity of habitats along the Treasure Coast.

The IRMCD office is located at 5655 41st Street which is just north of Vero Beach, Florida USA. The District can be reached at 772-562-2393 or by e-mail at This email address is being protected from spambots.

As an independent taxing district, IRMCD has three elected commissioners who provide policy and financial oversight. Management of daily operations is handled by the Director and Staff of 29 employees.

IRMCD employs an Integrated Pest Management (IPM) approach to controlling mosquitoes with the District. This includes extensive surveillance for mosquito populations, source reduction work via impounding to suppress saltmarsh mosquito production, larviciding to control immature saltmarsh mosquitoes, adulticiding to control flying mosquitoes and a surveillance program to detect and respond to mosquito-borne diseases in our area such as St. Louis encephalitis, West Nile virus, dengue and Zika.

The District also participates in research projects which over the years has investigated ecological impacts and solutions to our control methods, evaluating pesticides and application methods for efficacy, and testing to determine if local mosquitoes may be developing resistance to pesticides that we use.

While many people typically associate local mosquito control with night-time truck spraying, it is much more than that being an integrated approach to controlling mosquitoes for the comfort and health of our residents and visitors, all being accomplished within the framework of federal and state regulations.
